WINDOW APPLIANCE.

tSYSZSGlFlCATION forming part of Letters Patent No. 709,532, dated September 23, 1902.

Application filed August 29, 1901. Serial No. 73.720. (N0 model.)

To all whom, it may concern.-

Be itknown that 1, CHARLES E. BRAnsHAw, a citizen of the United States, residing at Cleveland, inthe county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Window Appliances, of which the following is a specification.

This invention relates to a combined window lock and hinge, and has for its objects the production of a device of this character which is strongin construction, convenient in operation, and economical in manufacture. These objectsI attain by the structure shown in the accompanying drawings, in which Figure 1 is a perspective view ofa window having my invention applied thereto, the hinge and lock appearing at the left thereof. Fig. 2 is a view taken through the right-hand side of the window -sashes when they are locked together and looking toward the left. Fig. 3 is an enlarged detail view of the window hinge and lock. Fig. 4 shows in perspective some of these parts detached from the window. Fig. 5 is a perspective view of the button for joining the upper and lower sashes. Fig. 6 is a similar view ofamodified form thereof; and Fig. 7 is a view similar to Fig. 3, but showing the hinge-piece swung about over the lower sash to hold it closed.

The cleaning of windows, especially in large office-buildings, is a task that has always been attended with an element of great dan- I ger owing to the fact that it has been necessary for the person doing the cleaning to get out over the window-ledge in order to reach the outside of the window-panes. Numerous attempts have been made to overcome this danger by providing the windows with hinge attachments, whereby the sashes may be swung within the room, so that the outsides of the panes can be cleaned; but owing to various mechanical imperfections none of these devices have proved commercially successful. My invention aims to overcome these defects and to provide a device which may be used as ahinge to swing the window when it is to be closed or to constitute a lock for the windowsash when it is closed.

In the drawings, in which similar reference characters designate corresponding parts throughout the several views, 1 represents the casing of a window, which is provided with the upper sash 2 and lower sash 3, said sashes being held in position by the stops or heads 4 and 5, respectively. As is usnalatthe present time these sashes are supported by cords b, which pass over pulleys 7, arranged within the window-casing, and have weights (not shown) attached to their opposite ends.

For the purpose of swinging the lower sash 3 within the room I place on the stop or bead 5 the stud members 8 of the hinges in such position that they mayengage with the socket members 9 on the inside portion of the lower sash 3. The stud member 8, which is shown in detail in Fig. 4, is by preference triangular in its general contour, the button 11 being at one angle and the stems upon which the member In rns being at the othertwo angles. This figure also shows the hinge-pieces 10, in which the'said member is pivoted. These hingepieces and the stud member areentirelyseparate until they are assembled and secured to the window-stop. The hinge-pieces are made into rights and lofts, as shown, depending upon the position of the recesses for the stems of the stud member, and these stems are pre cisely alike, so that either one may be turned up or down. By this structure the hinges are reversible and may be placed at either edge of the window-sash desired.

As is shown in Figs.l and 3,the stud member is normally turned backwardly from the sash 3, so as to lie practically in the plane of the hinge-pieces 10 and parallel with the stop 5. hen in this position, the sash may be raised and lowered without any interference with the hinge members. When, however, it is turned at right angles to this position, the button 11 on the stud member is broughtinto contact with the inner surface of the sash, so that when the latter is lowered the button will enter the slot 12 of the socket member 9, and the two members thus connected will form a hinge upon which the window-sash may be swung inwardly. It will be understood that the stop 5, which is opposite the hinge, will have to be removed so as to permit the sash to move inwardly at that side. It will also be evident that the sash must be supported by the hinges some little distance above the lower part of the window-casing, in order that it may clear the lower stop 13 when the sash is swung. For this reason the socket member is normally in a lower position than the stud member, so that the sash must first be raised, the stud member swung at right angles, and the sash then lowered in degrees from the positions shown in Figs. 1

' against the face of the sash. The spurs,which apart, and nothing projects therefrom to preon the upper outside portion of the lower order to bring the hinge members together. By placing the upper stud member just above the upper edge of the lower sash it may be turned back through one hundred and eighty and 2, when it will project over the lower sash when it is down to form a lock therefor. Fig. '7 shows the member 8 in this position.

The socket member 9 consists of a plate having an upper flat portion and a lower projected portion, with the U-shaped slot open at the lower end, and the side flanges having at their lower ends extensions forming spurs 14 to enter the sash, while the plate rests vent the full movement of the stud and socket members,and thewindow can be fully opened.

In order to bring the upper sash within the room, I temporarily secure the same to the outer side of the lower sash, when it may be swung inwardly therewith. These. parts are secured, as is shown in Fig. 2, by placing one of the socket members in an inverted position sasl1,close to its right-hand edge. This memher so located is shown in section at 15. Mounted on the inner and upper portion of the upper sash and in a position to engage with the member 15 when the sash is lowered isa button-piece 16,the button of which enters the slot in the member 15, as was described with reference to the button 11. As there is but one of these pairs of members connecting the sashes and it is near one edge thereof, the opposite edge must be supported by the sash-cord which acts as a hinge for the upper sash. The button-piece 16 is preferably provided with an extended flange or plate 17, through the outerportion of which ascrew is adapted to be inserted to hold the button from rotation. Whilethis screw also assistsin holding the button-piece in place, said piece is mainlyheld by means of a screw 18, which is madeintegral with the rest of the said piece, and preferably in line with the button thereon. In applying this piece to the window it is merely necessary to screw the same thereto until the plate 17 contacts with the sash, when the screw isinserted through said plate, which will prevent any reverse rotation. Fig. 6 shows a modified form of this button-piece in which the screw 18 is dispensed with and the plate 17 carried to the opposite side of the button, where it is also provided with an opening for a screw.

pivotal portions and the button of the member being at the apices of a triangle and the hinge-pieces being spaced apart opposite the button, and a socket member carried by the window-sash in position to engage with the stud member when it is in one position to form a hinge.

2. In a window-hinge, a stud member having a button, a pair of hinge-pieces secured to the window-frame in which said memberis pivoted, a socket member carried by the window-sash, said member comprising aplate with a fiat portion and a projected portion having a U-shaped slotand side flanges-extending into securing-spurs which enter the sash, against the side of which the plate is set and secured by screws through the flat portion, substantially as described.

3. In a window-hinge, a stud member having a button, separate hinge-pieces secured to the window-frame in which said member is pivoted, the pivotal portions and the button of the member being at the apices of the triangle and the hinge-pieces being spaced apart opposite the button, a socket member carried by the window-sash, said member having an inverted-U-shaped socket in position to engagewith the button on the stud member, and spurs projecting from the rear of the socket member on each side of the socket for assisting in holding the member to the sash, said socket members being projected in front and hollowed out at the rear to receive the head of the button without recessing the window-sash.

4. In a device of the character described, a lower and an upper window-sash, means whereby the lower sash may be swung about one of its edges, a plate secured to the rear side of the lower sash, said plate being coneaved on its inner side and having a U -shaped notch opening upwardly therein, and a but ton secured to the upper sash above the said plate for the purpose specified, said button having a flange and a screw integral therewith, and said flange being provided with a hole for a screw by which the button may be prevented from turning.

In testimony whereof I atfix my signature in the presence of two witnesses.

CHARLES E. BRADSHAW.
